Leonardo,
Earlier you said that a statement without a parameter ('?') works, but
one with a parameter doesn't.
In both cases, are you still using a PreparedStatement?

yes, it is always a preparedstatement.

You probably shouldn't have setup your database structure like that.
You should always break out multiple values into a separate table, each

I guess you are stuck building your list with application code, then. You
